First of all, the rulers have different ideas. The Mongolian rulers of the Yuan Dynasty did not regard the people of the Song Dynasty as their own at all, but also regarded themselves as outsiders. For the Song people, they want to rob and kill. It can be said that the rulers of the Yuan Dynasty did not regard the Song people as human beings at all, but regarded them as their own cattle.

Secondly, the rulers of the Qing Dynasty were just the opposite of those of the Yuan Dynasty. Since the Manchu entered the customs, I have been afraid that my rule will not last long. Therefore, the previous emperors since entering the customs have tried their best to study Chinese culture, hoping to understand the ideas of the Han people and try to reach an agreement with them to stabilize their rule.

Finally, the rulers of the two dynasties had different ruling strategies. The Mongolian rulers of the Yuan Dynasty, out of hatred for the people of the Song Dynasty who rebelled against themselves, have implemented extremely strict tax policies since they came to power, with no regard for people's lives. After the Qing rulers came to power, they widely implemented benevolent policies and reduced farmers' taxes, thus winning the hearts of the people.
